Abstract: According to one embodiment, an IC card which makes a non-contact communication with an external apparatus, includes, a reception module configured to receive a first command transmitted from the external apparatus, a determination module configured to determine whether or not the first command is a switching request command which requests to switch the IC card from a passive mode to an active mode, a command generation module configured to generate a second command which controls other IC card to execute processing when the first command is the switching request command, a command transmission module configured to transmit the second command to the other IC card.

Abstract: According to an embodiment, a smart card includes a communication section and a control section. The communication section communicates with the external device. The control section sets up a first speed as the communication speed used for communication with the external device by the communication section. Moreover, the control section changes the communication speed from the first speed set up to a second speed specified by a change request when the control section receives the change request of the communication speed from the external device by the communication section.
